1. Evaluate

if x = 2.5 and y = ?1.5.

2. Evaluate

if a = 4, b = 3, and c = 2.

For Questions 3 and 4, evaluate each expression if a = 3.5 and b = ?10.

3. ? |b + 2a|

4. |?3 ? a| ? 5. Use I = prt, the formula for simple interest over t years, to

find I when p = $2000, r = 6%, and t = 18 months.

Name the sets of numbers to which each number belongs. 6.

7. ?2.5

8.

For Questions 9 and 10, name the property illustrated by each equation.

9. 3ab + (?3ab) = 0 10. 1xyz = xyz

11. Simplify (10x ? 15) + 4(2x ? 5).

12. Write an algebraic expression to represent the verbal expression five times the sum of seven and a number.

Solve each equation. 13. 5n ? 3 = 12 14. 7x ? 10 = 4 x + 11
